Mühlacker biomethane plant integrates advanced substrate preparation
Mühlacker biomethane plant was established in 2007 as a subsidiary of the Mühlacker Department of Public Works. One of the first plants in Baden-Württemberg to incorporate its own gas preparation plant, today it is the hub of a thriving regional circular economy. The plant processes feedstock from around 120 local raw material suppliers to produce high-quality universal fertilisers for horticulture and biomethane. The treated biogas is fed directly into the public natural gas network, supporting a decentralised energy supply.
The plant generates up to 5 MW of gas power and 2 MW of electrical power, and an annual processing capacity of 30,000 tons of fresh material. The feedstock ranges from traditional maize silage, grass and cattle manure to straw, so the plant must be capable of handling a wide variety of substrates. This versatility is becoming more important as biological residues replace energy crops. The increased use of long-fibre substrates such as straw and manure, which often contain contaminants like stones, requires new engineering solutions.
